The breed of Hucul horses is valued for its strongly consolidated features. In a small closed animal population such as Hucul horses is, the knowledge of inbred level and its constant monitoring are very important. The base of inbreeding coefficient calculation is animal´s pedigree. One of the most important sire lines of hucul horses is the Gurgul´s line. Its first specimen in Poland was Cukor-Gurgul-5 stallion. For years, his mother´s pedigree remained unknown in Poland. This work confirms the existence of missing documents in Czech, and their connection to the said specimen.
